If you ever wanted to know what Emirates offers to its First Class passengers, Jaunted has a list.

My favorite in the men's option? The leather kit itself. (photo credit: Jaunted)

The pajamas are amazing. I still have two pairs.

Note that these are only given on long-haul overnight flights (I've been upgraded once on a LHR - DXB: 6h45m but as it was a daylight flight, there was no amenity given, though you can probably kindly ask).
